The immune system serves as the body’s defense against infections by microorganisms; damage caused by other foreign substances; and the uncontrolled, tumorous growth of the body’s own cells. Impairment of this system can increase a person’s risk for developing various illnesses, including infectious diseases, such as tuberculosis, and certain types of cancer. Alcohol can modulate this defense, and clinicians have known for a long time that chronic alcohol abusers have an impaired immune system. For example, alcoholics are prone to infections by various disease-causing microorganisms (i.e., pathogens); have a decreased ability to fight these infections; and have an increased risk of developing tumors, particularly in the head, neck, and upper gastrointestinal tract. Although alcohol-induced malnutrition—including vitamin deficiencies—and advanced liver cirrhosis likely contribute to some abnormalities in the immune system of alcoholics, alcohol itself also is a potent modulator of immune functions. Interestingly, not only chronic alcohol abuse but also single-episode (i.e., acute) and/or moderate alcohol consumption can affect the immune system.

These increased cytokine levels may contribute to most of the signs and symptoms observed in patients with alcoholic hepatitis (e.g., generally increased metabolism, fever, weight loss, elevated levels of proteins produced in the liver, and markers of malnutrition). It is unknown, however, which cells cause the elevated inflammatory cytokine production in alcoholics. As you abstain, natural killer cells regain their optimal function, improving the body’s ability to fight off infections. The overall inflammatory burden decreases, reducing the risk of chronic diseases.

Alcohol also impairs immune cell function and weakens epithelial barrier function in the lower airways, which can cause bacterial respiratory infections. Having a fully functioning immune system is crucial to successful chemotherapy treatment, so a person’s body may not handle or react to conventional chemotherapy as well if they drink alcohol. The spike in alcohol sales has alarmed health experts and officials around the world, who are concerned that increased drinking could make people even more vulnerable to the respiratory disease. While alcohol can significantly affect the immune system, many alcohol-related diseases can affect other parts of your body. Most alcohol-related diseases are more likely to occur in someone who has been using alcohol chronically.

Opposing Effects of Alcohol on the Immune System

Additionally, the role of alcohol-induced changes in the microbiome on immunity should be studied. Recent studies have shown that the microbiome modulates immunity in the gut, and in turn, immunity modulates the microbiome in the gut (Belkaid and Hand 2014). Only two studies have examined alcohol-induced changes in colonic (Mutlu, Gillevet et al. 2012) and fecal microbiomes (Chen, Yang et al. 2011), and both studies focused on individuals with AUD. For instance, IL-1 induces HPA axis activation and glucocorticoid release that suppresses the immune system (Sapolsky, Rivier et al. 1987). Cytokines are also proposed to cross the blood-brain barrier and produce sickness behavior (Watkins, Maier et al. 1995), which is comorbid with AUD (Dantzer, Bluthe et al. 1998). Ethanol administration (4g/kg) in male rats increased IL-6 but decreased TNF-α expression in PVN, an effect that was blunted or reversed after long-term ethanol self-administration (Doremus-Fitzwater, Buck et al. 2014).

• All of the studies about alcohol’s effect on health are observational—meaning that researchers have participants report their behavior (in this case, drinking amount or frequency) and discern health outcomes through self-reporting or medical records.
• They’ll likely monitor you closely for signs and symptoms of infection during treatment.
• “Anything above that, regardless of time period, is exposing your body to more alcohol than is ideal,” says Favini.
• For example, when you stop drinking, your brain can repair damaged neurons and rebalance the neurotransmitters.
• Researchers also have found, however, that the cytokine gamma-interferon (IFN-γ) plays a critical role in determining whether a Th1- or Th2-type response will dominate in alcohol-exposed monocytes.

Symptoms

It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers. Ethanol is primarily metabolized in the stomach and liver by alcohol dehydrogenase (ADH) and cytochrome P450 2E1 (CYP2E1) (Zakhari 2006). ADH is present in the cytosol whereas CYP2E1 is present predominantly in microsomes. Both enzymes convert alcohol to acetaldehyde, which is further metabolized to acetate by acetaldehyde dehydrogenase (ALDH) in the mitochondria.

Because of those negative effects, people who suffer from an alcohol use disorder (AUD) or drink too much too often are more susceptible to diseases and infections. Alcohol addiction delivers a devastating one-two punch by both hindering the body’s defenses and leaving organs vulnerable to disease. While binge drinking is typically more harmful than occasional drinking, any amount of alcohol can have adverse effects on the body and its ability to fight infections and diseases. Drinking every day or drinking too much alcohol at a time may affect the immune system more than drinking every other day or every few days, but the healthiest thing to do is abstain from drinking completely. Molecular mechanisms of the dose-dependent effects of alcohol on the immune system and HPA regulation remain poorly understood due to a lack of systematic studies that examine the effect of multiple doses and different time courses.

Alcohol is a common cause of liver disease because the liver filters alcohol. Each time a person drinks alcohol, some of the liver’s cells die, and new ones regenerate. Over time, heavy drinking can reduce a liver’s regenerative abilities and lead to alcoholic liver disease (ALD).

Healthy habits, such as being active, eating a balanced diet, and getting enough sleep, can keep your immune system strong. But unhealthy factors, A Guide To Sober House Rules: What You Need To Know like stress, smoking, or drinking alcohol, can be taxing for your immune system and make it harder for it to fight off infection. A weakened immune system makes it more difficult for your body to fight off infection. As a result, if you are exposed to certain infections, you are more likely to get sick.

Alcohol also reduces sleep quality, which increases a person’s chances of getting sick and recovering from illnesses. Adequate sleep helps the body fight off infections and viruses, and the less sleep you get, the less your immune system can protect your body. According to the Cleveland Clinic, once you take a sip of alcohol, your body prioritizes breaking down alcohol over several other bodily functions. The body doesn’t have a way to store alcohol like it does with carbohydrates and fats, so it has to immediately send it to the liver, where it’s metabolized.

• Thus, alcohol may interfere with antibody production indirectly by inhibiting the production of certain T-cell–derived cytokines required for B-cell function.
• Similarly, the TNF-α levels produced in response to a challenge with a bacterial antigen were decreased in mice that had received a single dose of alcohol.
• The immune system is how your body defends itself from infections — like harmful bacteria and viruses — and prevents you from getting sick.
• Even moderate consumption—no more than one alcoholic beverage per day for women, and no more than two per day for men—comes with dangers, and the situation snowballs the more a person sips.
• Other studies investigating alcohol’s effects on the susceptibility to infections with Klebsiella pneumoniae and Legionella pneumophila indicated that chronic alcohol treatment suppressed the production and/or function of neutrophils and macrophages.

But even moderate alcohol intake can compromise immune responses, making people more susceptible to infections. Similarly, an increased percentage of CD8 T cells expressing HLA-DR and CD57 was reported in the group of male alcoholics with self reported average alcohol consumption of approximately 400g/day for approximately 26 years (Cook, Ballas et al. 1995). Taken together, these studies suggest that chronic alcohol-induced T cell lymphopenia increases T cell activation and homeostatic proliferation resulting in increased proportion of memory T cells relative to naïve T cells. In contrast, moderate alcohol increased frequency of lymphocytes (Figure 1). In summary, several in vitro and in vivo studies demonstrate that ethanol modulates the function of innate immune cells (monocytes and DCs) in a dose and time dependent manner (Figure 1).

Post-mortem studies of chronic drinkers have found that they tend to have less immune cells in their blood than non-drinkers. Alcohol can suppress our innate immunity, which serves as the body’s frontline defense. This means infections like colds or the flu might last longer if alcohol has been consumed, as the immune cells’ ability to combat these pathogens is hampered. Alcohol, when consumed regularly and in excess, can weaken the immune system. It can interfere with the immune system’s ability to fight off pathogens, reduce the production and function of immune cells, and even trigger inappropriate immune responses. While enjoying a single drink might not sound the alarms throughout the entire immune system, even moderate drinking can extend the time it takes your body to recover from illnesses.
